When a metallic powder is subjected to a suffkiently high pressure a certain amount of adhesion takes place between individual particles. If this compact i s then sintered the bond is improved by diflusion and intergranular grain growth. The earliest known platinum objects were fabricated by such a powder metallurgical process, and when European scientists first addressed the problem of manufac...

The purposes of this investigation were to determine the effect of nitrogen on the strain aging and brittle ductile transition of iodide vanadium and to determine the basic mechanisms responsible for the occurrence of these results.

Light weight materials coupled to the need for cost-effective processing have combined to create a significant opportunity for aluminium powder metallurgy as its increasing interest. Aluminium alloy (AA 2219) metal matrix composite reinforced with multi walled carbon nanotube (MWCNT) produced by powder metallurgy (P/M) technique was analysed and CNTs dispersion were traced. The micro hardness a...

Solution Precursor Plasma Spray (SPPS) technique is an emergent technique which offers significant performance advantages with various functional coatings like YSZ, ZnFe2O4, LSM, metal-doped ZnO, etc. Apart from the above capabilities, efforts towards development of an innovative hybrid approach through simultaneous deposition of powder and solution resulted in coatings with unique microstructu...

Measurements which show the potential for corrosion of a plant’s metallurgy due to interaction with the system water have gained in importance within the last two decades. Among the most successful of these measurements are those which measure an actual potential which is based upon the oxidation/reduction reactions taking place. The measurement of Oxidation Reduction Potential (ORP) has been u...

Just like soldering, wire bonding appears to be a simple process and is frequently taken for granted. People tend to think all that is required to have a high quality bonding process is a simple wire pull test to monitor and control the process. But like soldering, this process is complex and requires a thorough understanding of the metallurgy, thermodynamics, and surface chemistry involved. Th...

Metal matrix composites (MMCs) have become attractive for engineering structural applications due to their excellent specific strength property and are increasingly seen as alternative to the conventional materials particularly in the automotive, aerospace and defence industries. Al/SiC MMC has aluminium matrix and the silicon carbide particles as reinforcements and exhibits many desirable mech...

This paper concerns the domain of contracts in the metallurgy and heavy industry, that are the form of deals making between cooperating companies being suppliers and consumers of some goods. From a general point of view cooperation enables for small companies to realize orders that are too large for an individual producer, but contract negotiations, further scheduling and support of production ...
